Definitions
- Passive optical networks are becoming prevalent in part because service providers want to deliver high bandwidth communication capabilities to customers. Passive optical networks are a desirable choice for delivering high speed communication data because they may not employ active electronic devices, such as amplifiers and repeaters, between a central office and a subscriber termination. The absence of active electronic devices may decrease network complexity and/or cost and may increase network reliability.
- FIG. 1 illustrates a network 100 deploying passive fiber optic lines.
- the network 100 may include a central office 110 that connects a number of end subscribers 115 (also called end users 1 15 herein) in a network.
- the central office 110 may additionally connect to a larger network such as the Internet (not shown) and a public switched telephone network (PSTN).
- PSTN public switched telephone network
- the network 100 may also include fiber distribution hubs (FDHs) 130 having one or more optical splitters (e.g., l-to-8 splitters, l-to-16 splitters, or l-to-32 splitters) that generate a number of individual fibers that may lead to the premises of an end user 115.
- the various lines of the network can be aerial or housed within underground conduits (e.g., see conduit 105).
- the portion of network 100 that is closest to central office 110 is generally referred to as the Fl region, where Fl is the "feeder fiber" from the central office.

Since breakout locations are often provided at mid-span locations on the main cable being accessed, it desirable for field mounted enclosures to be readily mountable at mid-span access locations without requiring the main cable to be "threaded" lengthwise through the enclosure.
- optical splices
- Fiber optic networks can extend to multi-dwelling units such as apartment buildings and condominiums.
- FIG. 2 shows a fiber optic network including a cable 150 routed into a multi-dwelling unit 152.

- the drop cable 418 exits the enclosure through a cable pass-thru fitting 225 disposed on the cover 216 of the enclosure 202.
- any excess fiber optic cable 400 disposed in the first cavity 266a of the base 214 is wrapped around cable management spools 420 disposed in the base 214. With the excess fiber optic cable 400 coiled around the cable management spool 420, the fiber optic cable 420 exits the enclosure 202 through the cable opening 270 disposed on the second end 212 of the base 214.
- the cover 216 is then engaged to the base 214.
- the cover 216 is sealing engaged to the base 214.
